IMPROVEMENT IN COFFEE-POTS.

Specification forming part of Letters Patent No. 35,022], dated April 23,1869.

T0 aZZ whom itJimy concern:

Be it known that we, NoR'roN l). HARTLEY and MARCUS S. MOREHOUSE, both of Quincy, in the county of Adams and State of Illinois, have invented a new and Improved (.oifee- Pot; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the an nexed drawings, making a part of this specification, in which- Figure l is a vertical central section of our invention. Fig. i is a detached side view of a port-ion of the same.

Similar letters of reference indicate corre sponding' parts in the two figures.

To enable those skilled in the art to make and use our invention, we will proceed to de scribe it.

A represents the body of lhe cotl'ee-pot, which may be constructed in the usualorany proper way, and provided with a nozzle, B, having a cap, (I, on its upper end. A is also provided with a handle,

l") is a cylindrical vcssehwhich is considerably smaller in diameter than the body A of the pot, and has a strainer, l, fitted on its lower end, and also a box, F, the latter being perforated, as shown at b, the perforations being just below the strainer E, as shown clearly in Fig: l.

The vessel D has a cylindrical box, G, at-

tached to its upper end, which is larger in diameter than the vessel D. The box G has a flange, c, at its lower end, and this flange tits snugly into the top of the body A of the pot, while the vessel D extends some distance up within the box G, the former being provided with a lid, (1, as shown in Fig". 'l. The box G is also provided with a lid, e.

H is a tube, the upper end of which is curved or bent and extends into the upper part of the vessel D, while the lower part extends down within the body A of the pot and The body is provided wilha flaring end, I. (Shown more particularly in Fig. 2.) A pipe, J, passes through the bottom of box G at the outer side of vessel D and forms a communication between the boX G and the interior of the body A of the pot.

The operation as follows: The ground coifee is placed in the vessel D and the water is poured into the body A of the pot, the cap a being; fitted on spout B, and the lid (1 fitted on the vessel D, and the lid 6 011 box G. The water in A, while boiling, extracts the strength from the coffee at the lower end of the vessel D, and consequently the cottee is immersed in the water in A. The steam is not allowed to escape from the body'A, but passes up through pipe ll into the vessel D, where it condenses. The pipe J admits steam into the box G, and prevents the lid (1 being removed by the pressure of steam in the vessel I). Said pipe .I also serves an escape or safety pipe in case of the too rapid and forcible generation of steam, for when the pressure of steam is too great the top 6. will be lifted from the chamber G. By this arrangement the aroma of the cottee is not allowed to escape from the pot, and all sediment which may pass through the strainer E will settle in the box F, the. holes I) being a considerable distance above the bottom of box F.

Having thus described our invention, we claim as an improved article of manufacture A coffee-pot provided with pipes .I H, chamber G, vessel D, strainer I, and box F, and otherwise made as herein shown and de scribed.
